STEPHEN JAMES COATNEY, OF FALLON, NEVADA.

BILLING-PRESS.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed April 30, 1918. Serial No. 231,651.

To all whom it may concern:

Be it known that I, STEPHEN J AMES COAT- NEY, a citizen of the United States, and a resident of Fallon, in the county of Churchill and State of Nevada, have invented certaln new and useful Improvements in Baling- Presses, of which the following is a specification.

My invention is an improvement in baling presses, plunger formed from sheet metal, together with new and improved means for operating the same, which may be driven from a motor mounted upon the press.

In the drawings:

Figure 1 is a longitudinal section of the improved baler;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a perspective view of the plunger.

In the present embodiment of the invention, a suitable frame 1 is provided,'the said frame being formed in the usual manner of angle plates arranged at the corners of the frame, the angle plates being connected at their ends, and a baling chamber 2 is arranged intermediate the ends of the frame. This frame is supported by a rear axle 3 and a front axle 4, and wheels 5 are mounted on the axles. The front axle is mounted to turn with respect to the frame in the usual manner in order to guide the frame, and within the baling chamber is mounted to reciprocate a plunger, shown more particularly in Fig. 3.

This plunger comprises a plate 6 which is the plunger proper, and this plate is "connected to a second plate 7 arranged at right angles to the plate 6, the plate 7 forming the stem of the plunger. Referring to Fig. 3, it will be seen that the plate 7 is of greatest width intermediate its ends, being cut away at its ends on each side-to form reduced portions, and one of these reduced portions is received between the outturned ends 8 of plates 9 which are secured to the plate 6. Each of these plates 9 has also an out-turned portion 10 at its outer end, the said portions being flush with the ends of the plunger and serving to guide the plunger and to prevent it from twisting in the baling chamber. At its widest portion the stem 7 has a vertical slot 11, and within this slot is mounted to move a block 12.

and has for its object to provide a' The block has its ends recessed to receive the side walls of the slot. This block is journaled on the crank 13 of a crank shaft 1 which is mounted to rotate in the frame in front of the baling chamber, and it will be obviou that when the shaft is rotated the plunger will be reciprocated, the slot 11 being long enough to permit the movement of the block necessary for this purpose.

The stem is guided in its movement by means of angle plates 15, each of which has a portion secured to the stem and a portion extending laterally therefrom. Four of the angle plates are provided, two on each face, and two at each end of the stem. The laterally extending portions of the angle plates move between the outwardly extending portions of angle plates 16 which are secured to the bodies of substantially yoke shaped brackets 17 supported by the frame members in the manner shown in Fig. 2. Four of the brackets 17 are provided, a pair in front and a pair behind the crank shaft, and each pair carries a pair of angle plates 16.

The members of each pair of brackets are arranged in register, and thus the plunger stem is guided. The baling chamber has the usual hopper shaped inlet 18, and the shaft 14 is driven in any suitable or desired manner, as, for instance, by means of a motor, which may drive a shaft 19 also journaled transversely of the frame. This shaft has a pair of sprocket wheels 20, one wheel at each end, and the wheel are connected to wheels 21 on the crank shaft by means of sprocket chains 22. This shaft 19 may be connected to the motor.

The shaft 23 of the motor 24 may be connected to the shaft 19 in any suitable or desired manner, and the motor may be used to propel the frame, being connected to the rear axle by means of a sprocket chain 28, which connects a sprocket wheel 29 on the rear axle with a sprocket wheel on the shaft 19.

I claim:

1. In a baling press, a plunger comprising a plate, a second plate secured to the first named plate intermediate the end of the said plate, said last named plate forming a stem and having the greatest width intermediate its ends and reduced at each end, said stem having a vertical slot at the widest at each side of each of the reduced portions,

and having flanges at the ends of the first the ends of the head plate, saidstem plate named plate, said ribs and flanges serving having longitudinally extending central ribs as guides. forming guides for the stem, the head plate 10 2. In a baling press, a plunger comprising. having flanges at its ends extending sub- 5 a head and a stem, the head and the stem stantially parallel with the stem.

being plates, the head plate being secured to one end of the stem plate intermediate STEPHEN JAMES COATNEY.
